Marine Winterisation Cost Calculator
Add your own costs for one marine winterisation season and compare each item’s share of the total.
A QUICK WALKTHROUGH
How to use this tool
- Name your currency and enter 1–100 labelled cost items for a single season.
- Use your own nonnegative amounts in the same currency; zero is allowed.
- Calculate the total, item shares and all items tied for the highest amount, then copy or save the report.
Calculation
Total = sum of amounts. Item share = amount ÷ total × 100. If the total is zero, every share is undefined. The highest amount includes every tied item.
One season
A list of costs you supply for one season. No currency conversion, year or month averages, market prices, or winterisation procedure advice.
Numeric precision
Uses JavaScript floating-point numbers. Raw inputs are retained in the report and results use JavaScript’s numeric precision without fixed currency rounding. Some decimals are approximate. Overflow, underflow, a positive addend swallowed by addition, and a nonzero share lost to zero are rejected.

GOOD TO KNOW
Common questions
What happens when all amounts are zero?
The total and highest amount are zero, all items tie for highest, and shares are explicitly undefined.
Are these amounts estimated for me?
No. Enter your own amounts and currency label; the calculator provides arithmetic only.
